Proximity (Backshelf) Hoods; Plate Shelf With Duct Enclosure Installation - Accurex XB Installation, Operation And Maintenance Manual

Proximity (Backshelf) Hoods

A proximity style hood is designed to be mounted close
to the cooking appliance
and typically incorporates
underhang instead of
overhang as utilized with
canopy style hoods.
The proximity design, in
addition to the hanger
brackets, may include a
back mounting flange.
Therefore, hanging the
hood differs slightly from
that of a wall or single
island canopy hood.
1. Locate the studs in the wall.
2. Drill 1/2 inch (13 mm) diameter holes in the hood
mounting flange. Be sure to align to wall studs.
3. Lift hood into a level position and lag bolt hood to
wall (fasteners by others).
4. Bolt 1/2 inch threaded rod into the remaining hanging
brackets.
5. Fasten threaded rod to the ceiling supports, then
level the hood.
If the proximity hood was provided with a back supply
plenum, the hood mounting flange may be fastened to
the back supply using sheet metal screws (by others).
Pilot holes are recommended.

Plate Shelf with Duct Enclosure Installation

If the proximity hood is provided with a plate shelf, this
will be factory mounted to the hood (shown loose in
figure below). Similar to the standard enclosure panel
installation procedures, make sure the hood is hung in
position with all the ductwork attached and fire system
and electrical connections completed before attaching
the enclosures.
1. Tack-weld or clamp end enclosure panels into place
(clamps provided).
2. Attach the end enclosure panels to the wall (fasteners
are not provided).
3. Position the front enclosure panel(s) on the hood and
bolt to the end enclosure with the 5/16 inch bolts
provided.
4. Tack-weld or clamp the front enclosure panel(s)
to the hood. If clamps are used, they must be
positioned 4 inches (100 mm) from the ends and in
the center of the front enclosure panel.
5. To allow for ease of cleaning, caulk the external
seams with NSF Approved silicone caulk (GE
SCS1009, or its equivalent). The caulk is not
provided.

Installation instructions may not be applicable for
